Trait INotifyDataErrorInfo 

pub trait INotifyDataErrorInfo {
    // Required methods
    fn has_errors(&self) -> bool;
    fn get_errors(&self, property_name: Option<&str>) -> Vec<BoxedValue> ;
    fn errors_changed(&self) -> &Event<str>;
}

Lets a model object report validation errors for its properties (synchronously or asynchronously).

Required Methods

fn has_errors(&self) -> bool

Whether the object has validation errors.

fn get_errors(&self, property_name: Option<&str>) -> Vec<BoxedValue>

The validation errors of the property named property_name, or the object-level errors when it is None or empty. Errors are untyped: strings and boxed BindingError values are shown as they are.

fn errors_changed(&self) -> &Event<str>

The event raised when the validation errors of a property (the event argument; empty for the whole object) have changed.

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
